A question came up on the VWNC list recently about teaching some simple physics modeling. Of course there's always EToys to look at as an example, but something else came to mind: ElastoLab, from Dave Buck:

ElastoLab is a fun program for kids that lets them play with sound, images and motion in a simulated physics environment. ElastoLab

It's a really cool simulator that lets you play with all sorts of variations on motion.

Update 4:Now there's confirmation - it looks like it is a government operation, with Immix doing the work. I'll return to my original question: how the heck is this the business of DHS?

“ICE office of Homeland Security Investigations executed court-ordered seizure warrants against a number of domain names,” said Cori W. Bassett, a spokeswoman for ICE, in a statement. “As this is an ongoing investigation, there are no additional details available at this time.”

Update 3: This may be the missing piece of the puzzle. Go back to this story from May 18, where we find out what Immix is up to:

So.... it looks like it's a federally backed operation, but run by the "cyber security" people at Immix Group. The only question is, how high up in DHS/ICE did the OK for this go? Did they have a bunch of pre-ok'd warrants about that they acted on, or did some kind of legal action take place late Friday? At this point, I'd like to see some real reporting done on this.

Update 2: - A look at the registrar information turns up a immixGroup IT Solutions - and it looks like they do a lot of work for the government. So.... is this some kind of pseudo government operation that jumped the gun? That would explain the ability to get the DNS redirected (the sites in question are being redirected via seizedservers.com DNS services), while also explaining the lack of any PR push. If you go to the whois lookup for seizedservers, you can get all of that info. Curiouser and curiouser...

Update: Ok, this now looks more interesting. Have a look at the source of one of the sites that's been taken down, like torrent-finder.com. The source doesn't have any of the "official government" stuff you would expect - and there's a script being loaded from 74.81.170.107 - which is located in North Carolina, and doesn't look at all like a government run operation. Or, if it is government, it's some kind of second hand contract sort of thing that could be denied. Since I'm not really in the conspiracy business, let's take the more obvious tack: it's likely that the RIAA or the MPAA (or possibly both) are paying someone else to do the dirty work that they couldn't get the government to do for them through the proposed COICA law. Or heck, it could be a set of pranksters out having a good time - right now, there's no telling. I think Drudge needs to dig a little deeper on this one.

Another thing - there are no press releases out from DHS or ICE. Typically, when a government agency does something like this, they announce it with great fanfare as an example of "protecting the country". Since there's none of that here, it makes me really wonder.

Hat tip to Michael, for prodding me on this and doing a bunch of the research.

The investigative arm of the Homeland Security Department appears to be shutting down websites that facilitate copyright infringement.

So what happens when the slower class at DHS figures out that domains can be set up beyond their jurisdiction? Does the US build its own version of the "Great Firewall of China", with the DHS acting as the muscle for the RIAA and MPAA?

It doesn't seem to matter who's in the Oval Office or the Congress; on copyright matters, the stupid never stops. Oh, and if you don't think this kind of siezure isn't open to easy abuse - you're not thinking hard enough. Just imagine that (insert partisan forces you distrust here) is in power, and apply the rhetoric you usually use on other issues...

Lukas has another highly descriptive post up on using his PetitParser:

In a previous post I described the basic principles of PetitParser and gave some introductory examples. In this blog post I am going to present a way to define more complicated grammars. We continue where we left off the last time, with the expression grammar.

As I said earlier, the slow learners over at DHS apparently aren't aware that they don't have jurisdiction over the entire internet. Market Ticker is quoted by TechCrunch:

That’s a lot of staff attorney time and trouble to get a big fat nothing out of it, which is exactly what they get going down this road. Why? Because all they can do is redirect the domain pointers which will do exactly nothing when the sites re-register under a top-level domain not under the US Government’s jurisdiction and there are lots of them.

Now we just have to wait for the coming justification for the "Great Firewall of the DHS". I'm sure that it will be "for the children"

We finally got back to board gaming last night - my friend Mike got me the game "Founding Fathers", and we sat down to a game - my brother in law was visiting, so it's nice that it handles 5 players. The game has you at the (US) Constitutional Convention, voting on the various articles for the document - and you end up working with the four main factions - big states, small states, federalists, anti-federalists. It's all pretty fluid, and your options change as you get your hand replenished with new delegates.

It played pretty well, and, once we got going, it was a simple game. The rules only look long because they include bios of all the convention attendees :) If you like strategy games that take 90-120 minutes to play, this one is pretty cool.

The copyright kings don't want you to know just how bogus their claims are - a lawyer who sells a $20 package of "FYI" documents, telling you how to defend against one of the fishing expeditions, is now being sued:

On November 22, Syfert received another email from attorney Jeff Weaver informing him that he had made a formal request for sanctions against him on behalf of the production company behind The Hurt Locker, one of the driving forces behind the USCG lawsuits. Weaver is apparently claiming that the 19 cases filed using the self-help package have cost his firm $5000 and he wants Syfert to pay.

How dare people find an inexensive way to deal with a bunch of overpaid lawyers with way too much time on their hands...

I've seen this complaint about running Smalltalk app servers before, and I'm sure I'll see it again:

Running headless is a bear. Updating (e.g., loading the latest version of the web server or fixing a security vulnerability) a headless image on a remote server is very difficult (one has to either have a VNC session running in the image or save the image, copy it to a local machine, update it, copy it back, start it up again.)

Well.... not so much. I run a headless server here, and it's pretty easy - I have an image that loads what it needs when it starts up, and I can kill and restart anytime I want. For patching, I simply have a patch directory, and an interface that lets me "poke" the system and load whatever it finds in the patch directory. Since it will only load from there, and only when I tell it too (i.e., there's no code being loaded from an input field), it's secure enough for what I do.

I could automate that more if I felt like it; having a process periodically scan the patch dir, load whatever is there and then delete it would remove a manual step, for instance. The larger point is, patching a running server is easy, and it's one of the truly cool things about running a Smalltalk server.

Those patches vn be very invasive as well - some of the patches I loaded in the past (on the blog I ran at Cincom, which is an ancestor of this one) changed the shape of objects in the image on the fly.

So no, you don't need VNC, or a headful image. All you need is a little planning :)

You probably noticed the lack of posting since early this morning - I've been busy teaching an Intro to VisualWorks class via webcast. I'll be doing it all week, so posting is going to be intermittant the whole week.

It's actually working better than I expected - we're using Adobe Connect Pro to deliver the live presentation/demo to people - I have a second monitor up so that I can broadcast the demo screen, and keep the meeting chat room up on the second screen. The quality has been pretty good, and we've been using skype for two way conversations as needed (we haven't been able to get that to work in the Adobe tool).

The screen sharing has worked quite well - while it's not as good as being there, it's pretty good. I think this is the future of training that I'm seeing this week :)

Update: - It's become clear that Comcast wants to charge Level 3 for customer requests for video (et. al.) that are not based on their XFinity system - so if a Comcast customer uses NetFlix, or streams from iTunes (etc), then Comcast wants to toss a tollbooth on that content. This is understandable, even if it is incredibly stupid.

Let's say that Level 3 told Comcast to go fish, and Comcast then broke all non-XFinity services on their network. Exactly who do they think would take the PR hit for the services that their customers pay for and wouldn't be able to receive? Here's a hint - none of their customers have even heard of Level 3, and Level 3 isn't the one with the phone lines that would start lighting up when this happened...

I've just had a look at the Amazon data transfer charges for November, and there's a good news/bad news aspect to it. The good news is that the videos and podcasts seem to be popular. The bad news is that popularity isn't free :)

So, starting tomorrow I'm going to kill the iTunes enabled video feeds for the Smalltalk and Javascript screencasts. The existing content will stay where it is, but I won't be tossing more into those feeds. I'll still be pushing content, but it'll all go to YouTube and Facebook - it'll all be available, and I'll keep updating the index pages, but the iTunes feeds will stop updating.

The bill is small now, but the trendline shows me what will happen if I keep pushing video there :) So thanks for watching, and you can keep watching - just look for it on the blog proper instead in the iTunes feed.

I did a search at Google today for “cars” and was shocked. Rather than list links allowing me to search for “cars” on Bing, Yahoo, Baidu, Voila, Naver and Yandex, Google instead favored its own search results. I’m glad the EU will be investigating whether this favoritism violates anti-trust laws.

Oh, the humanity. Next they'll tell me that media sites favor their own content, and that newspapers favor their own stories. It's just terrible; how are we poor end users supposed to handle it all? I mean, typing "bing.com" in the address bar instead of "google.com" is such a chore...

Here's another video from ESUG 2010, which was held in Barcelona, Spain, the week of September 13, 2010. In this presentation, Esteban Lorenzano talks about Reef - a JQuery Model/View project for Seaside. You can watch using the embedded player below, or follow this link to Vimeo.

The AJP adatpor is a server adaptor dedicated to connecting Seaside to Apache. You can't use it without Apache because it doesn't understand HTTP. Instead it uses the binary AJPv13 protocol which is more efficient and simpler to parse. The result is a lightweight adaptor without any external dependencies but Grease/Seaside. In the multipart parser special attention has been paid to avoid unnecessary copy operations. Streaming however is currently not supported.
